Abstract: Electrical power distribution system for supplying a set of fixed-frequency loads and a set of variable-frequency loads, includes a set of at least one fixed-frequency AC voltage generator and a set of at least one variable-frequency AC voltage generator, a DC distribution network supplying the variable-frequency loads by means of inverter stages, a first set of rectifier stages connected between the fixed-frequency generators and the distribution network, and a second set of rectifier stages connected between the variable-frequency generators and the DC distribution network. The first set of rectifier stages includes bidirectional rectifiers capable of providing a bidirectional transfer of power and protection means against fault currents connected between the bidirectional rectifiers and the distribution network.

Abstract: The invention relates to a supply system for a plurality of loads connected in parallel to a direct current supply bus. The supply system includes a DC supply bus and a plurality of supply lines connected in parallel to the supply bus and supplying the said loads. The supply system includes uncoupling and damping means that is adapted to decrease the unipolar signals travelling within the supply system while the loads are being supplied. The uncoupling and damping means includes at least one inductance arranged in series in at least one of the supply lines. Protective means (are also provided for protection in the event of a fault.
